COMBINED TIME AND NON-TIME LOCK.

SPECIFICATION forming part of Letters Patent No. 272,063, dated February 13, 1883,

Application filed July 10, 1882. (Model) To all whom it may concern:

Be it known that I, WILHELM KOCK, of Oincinnati, Hamilton county, Ohio, have invented a new and useful Time and Permutation Look, of which the following is a specification.

This invention is an improvement in looks whose .gombination or permutation mechanism is capable of being subjected to temporary control of clock-work.

The principal useful novelties of this invention are comprised in two parts, to wit:

The first part of my inven tion relates to a the combination formula, the clock-work, at

: soine predetermined period-say three. hours alter release of the combined detached lever and augle-bar-opeiates to disengage the detached lever from the angle-bar, so as to permit the lock to be opened without setting up the combination.

In the accompanying drawings, Figure 1 is an inside elevation of the look as it appears after the following operations, to wit: the timer set for release after a lapse of ten hours from winding up, the bolt thrown, and the combination gated. In this view the automatic pin is shown set for holding back or delaying the domination of the timer for a specified time-say two hours. Fig. 2 is a transverse section on the line 1 1. vation in which the spring-detent c is shown temporarilyretraoted by the automatic pin. Fig. 4 is a top view of the fence or dogging mechanism, the parts being in position they occupy'in Fig. 3, and the upper safe-bolt being removed. Fig. 5 is a similar elevation, sh owing the parts in the conditions they assume after discharge of the ordinary timer functions, and with the tumblers gated or set up in combination for retracting the door-bolt. Fig.

6 is a similar elevation, showing the parts in .iug being shown in section.

Fig. ,3 is a similar elebe opened by any person by simply turning of the knob or handle, without using the combination. Fig. .7 is a perspective view, showing a part of the lock-case with its pivoted anglebar. Figs. 8 and 9 show respectively my detached lever and my connecting-latch separated from each other and from the lock. Fig. 10 represents a portion of the outside of the safe-door in it's unlocked condition. Fig. 11 is a front elevation of the timer .motive mechanism or exterior adjunct, the barrel or hous- Fig. 112 is a rear elevation of the exterior adjunct, the ratchet pawls being disengaged. Fig. 13 represents a portion of the outside of the safe-door, the same being inits lo cked condition, and the ratchet-pawls beingengaged for winding. Fig. 14. is a rear elevation of the mainspring-barrel, from which most of the spring has been broken away, so as to expose the pawl which looks the mainspring-barrel to the arbor-sleeve, the pawl being shown retracted. Fig. 15 is a rear elevation of the exterior adjunct, the ratchetpawls being represented engaged. Fig. 16 represents a portion of the outside of the safedoor, the parts being in condition as follows,

to wit: the mainspring-barrel locked to the arbor-sleeve and the ratchet-pawls disengaged,

so as to permit the setting up of the combination without allowing the spring to run down. Fig. 17 is a similar view to Fig. 14, but with the pawl engaged so as to lock the main barrel to the arbor sleeve. Fig. 18 is an axial section through the exterior adjunct. Figs. 19 and 20 are enlarged views of the parts represented by Figs. 1 and 10, respectively.

A may represent part ofa safe-door fornished with usual or any suitable bolt-work, B, and having a single orifice, a, Fig. 18, for the arbor 0, whose inner extremity is made fast to the drive-wheel D of a customary or any suitable stack of tumblers, D, and whose square outer end protrudes through the door and occupies a corresponding orifice in the I ,more pawls, J, Figs. 12 and 15, hold in action by springs K, but capable of release by operating handles L of cams M.

Another pawl, 0,-pivoted to the inner wall of barrel H, and having a handle, 1?, enables the stem Eto be locked fast to the barrel H when desired, it being necessary that these d members form a single piece when the purpose is to manipulate the tumblers or to throw. or retract the bolt-work. The barrel .1 1 takes the form externally of a knob or handle, Q, Fig. 4, by means of which all the operations of the lock controllable from the outside are governed. I

The arbor O has geared connection R with.

the clock movement proper. (See Fig. 1.) A customary slack or stud connection of the two systems of gearing is provided in order to permit the manipulation of the tumblers and boltwork without interfering with the clock-work.

The clock-spindle W has separate pawl-and- I ratchet connections X and Y with two disks, Z

and I), each having its own proper stud-projection, z and b, for independent impingement upon spring-detent c, which has a notch, c,'

that, when the timer is set or placed on guard, engages under a lug, d, that projects from the angle-bar d, which is hinged or pivoted to the lock-wall at 0, Figs. 2, 4, and 7, and has the customary arm,f, for engagingin the gates or notches of the tumblers, there being a small lip or projection, f, on the arm f, as shown more clearly in Fig. 2, for a purpose to be presently explained.

' In order to enable the bolt-work to be moved by means of the knob Q from the outside without having the tumblers set up or gated, I pro vide a bar or detached lever, h, (shown detached in Fig. 8,) which has at its front end a projectiougi, adapted to engage with the drive-wheel D, as shown in Figs. 5 and 6, this lever being pivoted at its rear end to the bolt-work, as shown at g, Fig. 19. To,prevent this lever from engaging with the drive-wheel before the hour for opening has arrived, I secure to the face of this lever' h a'sliding latch, 1, (shown detached in Fig.9 and in position in Figs.4= and 19.) A small spring, m, Figs. 4 and 9, is applied in such a manner as to keep this latch l pressed forward, in which case its front end engages upon the projection f ofthe angle-bar, thus locking the lever h and the angle-bard together, so that the lever cannot engage with the drive-wheel, except when the tumblers are gated, in which case both the angle-bar and lever h drop together as one piece.

As shown in Figs. 7 and 19, the angle-bar is provided with an arm, 61, with which the springdetent c engages until released by the pin z of disk Z; but when the pin 2 is brought by the rotation of the disk against the detent c the latter is thrown back, so as not only to disconnect it from the arm (1' of the angle-bar, but is also forced against a pin, a, secured to the latch l, whereby the latch is drawn back off of the projection f, thereby unlocking the lever h from the an gle-bar 01, when the lever h is free to fall and engage with the drive-wheel, as

. shown in Fig. 6, and when this occurs the boltwork can be moved by turning the knob Q, eventhough the tumblers be not gated.

It will be observed that the pin bof the disk b is so-arranged or located in relation to the pendent arm of the detent c that, while it will move the detent far enough to release the arm 01 of theangle-bar,it will notmoveitfar enough to draw back the latch l, as is represented in Fig. 3, the pin b passing by and becoming clear of the detent before moving it far enough to draw. back the latch. It follows from this construction and arrangement of parts that the disks 1) and Z may be so set that the pinb will disconnect the detent c from the an gle-bar at any predetermined time, when by setting up the combination the door can be opened; but in case the combination formula has been lost or forgotten, or the person having charge of the combination should be absent, then as the clock-work continues its movement the pin a will, in a given time for which it may have been set, force back the detent, draw back the latch, and release the lever h from the angle-bar, when, as above stated, the door can be opened without gating the tumblers.

On the winding-stem E, I place a small pinion, 11, (shown more clearly in dotted lines in Fig. 20,) which engages with a larger pinion, 17, carrying on its face a graduated circle, and-c around the stem E is secured a stationary circle, 1', which has an index or pointer, 11, arranged to act in conjunction with the graduated circle on the pinion p, which serves to show how far the spring has been wound up,

ary.circle r, and. which serves to indicate, in 1 connection witha mark, s, on the circle, when the parts are in such a position as to permit the pawl O to engage with the stem E, these parts being suitably arranged in relation to each other when they are put in place.

It will be seen by an examination of Figs. 14 and 17 that the pawl O can look upon the stem E whenever the latter is turned so as to cause either of its four sides or faces to stand in line with the rectangular notch in the pawl, and therefore it is only necessary to so locate the index I? and the mark s as to show when the stem and pawl are in that position.

As the index it is fast upon and turns with the stem, it is obvious that there may be four I mechanism,

as the pawl may.

of the marks s on the circle, engage with the stem when either of its four faces are turned toward the pawl. If, however, instead of making the stem square at the point where the pawl O engages it, it should simply be flattened on its two opposite sides, then of course there would be but two marks made on the circle.

By thus arranging the operating spring within the dial or knob, as described, not only can it be got at in case of necessity without disturbing the lock or opening the door,-

bnt by disconnecting its barrel by means of the pawls J J the knob is left free to be utilized both as 'a dial for manipulating the tumblers and also as a handle for throwing the bolt-work, thus avoiding the necessity of making two holes through the door. It is, however, obvious that, if preferred, the spring and its pawls may be put in a case separate and apart from the knob and stillbe accessible without opening the door or breaking into the safe. It is also obvious that, instead of the sliding latch l for locking the lever 71. to the angle-bar, other forms of devices may be used and be made to accomplish the same result,

, the only requisite being that the device used,

whatever its form or construction maybe, shall be arranged to lock the two parts together and be operated upon by the time mechanism to disconnect these parts at the proper time; and hence I do not limit myself to the use of these special devices, as any mechanic skilled in the art, from what is herein shown and described, can readily substitute other forms or devices for that purpose.

Having thus fully described my invention, what I claim is- 1. In a combined time and non-time lock, the clock-workmotive apparatus, located exterior to the safe, substantially as described, whereby it is rendered accessible without distnrbing the clock mechanism.

2. In a combined time and non-time lock, the combination of the external mainspring consisting of mainspring G, barrel H, provided with ratchet-teeth, and pawls J, and winding-stem E, with pawl 0, all ar-;

ranged to operate substantially as described.

3. In a combinedtime anl non-time lock, the combination of the drive-wheel D, the lever h, with its latch Z, arranged to be released by the time mechanism, substantially as described, whereby the bolt-work is released from control of the combination mechanism at a predetermined time after the release of the combination from the domination of the timer, as and for the purpose set forth. t

4.. In a combined time and non-time lock, the combination of the fence mechanism, consisting of the angle-bar d, lever h, and latch Z, with the spring-detent c and its operatingdisk 11 12, substantially as set forth.

5. In a combined time and non-time lock having the compound fence consisting of the parts (1, h, and l,the spring-detent c, and the disk Z z, combined and arranged to operate substantially as and for the purpose set forth.

6. In a combined time and non-time lock havin g its time-motor arranged exterior to the safe or vault, the index mechanism consisting of the parts 02,19, and c,arranged to operate substantially as described. i

7. Ina combined time and non-time lock, the index t, secured to and rotating with the winding-stem E, in combination with a fixed point, 8, and the locking-pawl 0, all arranged to operate as set forth.

8. A hollow safe-knob constructed substantially as described, whereby it is made to serve as a case for the mainspring and its connecting devices, as adial for setting the tumblers, and as a knob or handle for moving the boltwork, as set forth.

In testimony of which-invention I hereunto set my hand;

WILHELM KOOK.
